RotoSub AB presents the world’s first Self Silencing Fan

Linköping, Sweden – June 16 2011 – Noise pollution from fans has always been a problem, but a solution is finally available. The novel RotoSub technology, RotoSub R-ANC, takes a completely new approach by addressing the problem at its source, enabling the fan to reduce its own noise.

RotoSub R-ANC is an active noise reduction solution that integrates fully into the fan itself. The solution dramatically reduces its noise without increasing the size of the fan or requiring any additional components.

“Customers are calling for smaller more efficient low-noise fans with a higher degree of integration freedom” said Lars Strömbäck, CEO of RotoSub. “By providing an easily integrated and quieter solution, our customers can focus more of their creativity into product design.”

RotoSub AB announced today that the RotoSub R-ANC technology will be presented in an invited paper at the INTER-NOISE 2011 Congress in Osaka, Japan. The congress is sponsored by the International Institute of Noise Control Engineering (I-INCE), and is co-organized by the Institute of Noise Control Engineering of Japan (INCE/J) and the Acoustical Society of Japan (ASJ).

In conjunction with our ongoing project with the Swedish Trade Council in Japan meetings will be held during the Japanese tour. If you want to schedule a meeting please contact Sylvia Strömbäck. A video preview, demonstrating the noise reduction capabilities of the technology, is available on the RotoSub web site, at
